CASE FOR TRANSPORTINGTPHOTOGRAPHIC PLATES.

SPECIFICATION forming part of LettersPatent No. 283,455, dated August21, 1883. Application filed Junc16.18S3. (n model.)

To all whom it may concern.-

Be it known that I, HENRY T. ANTHONY, residingin the city of New York,in the county and State of New York, have invented a new 5 and usefulCase for Transporting Photographic Plates, of which the following is aspecifica-a I tion, reference being had to the accompanying drawings,formingpart of the same, in which- Figure 1 is a centralverticalsection, and Fig. 2 a central longitudinal section, of a caseembodying my invention, the section in Fig. 1 being on linear m, Fig. 2,and the section in Fig. 2 being on line 3 y, Fig. 1. i Fig. Sis a sideview, looking down upon the open case, the coveror lid being thrownopen; and Fig. 4. is a detached view, in section, of a portion of acover and one of the sides of the body of the holder, showingmodification of the joint between the lid and said body for theexclusion of light from theholder.

' By the use of what are known as dry plates, it is common to takephotographic negatives in the open air and elsewhere at a distance fromthe darkened room in which such plates are prepared or developed. Thepractice of this open-air photography requires the use of a case orother receptacle in which a number of plates may be inclosed andtransported -i'ro1n the light. In order to exclude the light from theplates while they are being transferred from the case to theplate-holder of the camera, the practice is to place the case in a darksack that is provided with arm-holes, through which the-operator thrustshis arms, having placed in the sack, beforeclosing its mouth, theplateholder also; then, guided by the sense of feeling, he opens thecase and withdraws a plate, and puts it into the plateholder and closesthe case. He may then open the sack and take out the holder containingthe plate to be exposed in the camera. After the exposure the plate isreplaced in the case by again placing the holder in the sack, ex eludingthe light and transferring the plate from the holder to the case. At thesame time that an exposed plate is thus replaced a fresh platemay betaken from the case and placed in the holder.

My invention relates to the case referred to;

50. and it consists in the improvements upon the hinged to the body, thehinges (r. a of each being preferably on the opposite side of t-hebodyfrom the other, as shown in the drawings, so that the sides will. openin opposite directions. In grooves cut in the open edges of the sidesand ends I insert strips of rubber I), that stand alittle above thelevel of the said edges. The

lids, when closed, press upon these rubber strips and effectuallyexclude all light from the case. If preferred, the grooves in the sidesand ends may be made semicircular, and corresponding ribs secured to thecovers, which fit into the grooves when the lids are closed, asseen inFig. 4. The lids may be provided with mouldings around their edges, asseen plainly in Figs. 1 and 2, which shut down over the edges of thesides and ends. 7 5

D is a plate, of wood or other suitable material, that corresponds inlength and breadth with the length and breadth of the case, and fitsloosely, so as to slide up anddown therein.

0 is a notch cut in the edge of the front side of the case opposite thehinges of the lid, through which the top plate of the series in f thecase, when the case is full, maybe reached by the insertion of thefinger or thumb nail to lift the top plate for removal from the case.

5 (I, Fig. 1, is a piece of rubber inserted in the cover, so arrangedthat when the cover is closed the rubber will fit down into the saidnotch and close it against light.

In using this case I proceed as follows: The 0 lid 0 being opened andlid 0 closed, with the plate D lying down upon the latter, as seen inFigs. 1 and 2, the case is filled with plates, as shown in said figures,and the lid C closed and secured by a hasp or hook, 0. Then, when at 9 5the place where they are to be exposed in the camera, the case, togetherwith the plate-holder, is placed in asack, before described, the lid 0opened, and the top plate, f, removed and. placed in the holder forexposure. After exposure the holder is returned to the sack. The casenow being reversed the lid 0 is Opened and the exposed plate is laid inupon the plate D and the said lid again closed. Then the case is againreversed to its first position, the lid 0 again opened, and anotherphotographic plate removed and transferred to the holder, to be in turn,after exposure, returned to the opposite side of the plate D until allare in turn transferred from one side of the plate D to the other. Bythese means, as is obvious, an unexposed plate will at all times bepresented at the top of the ease within reach of the thumb or fingerthrough the notch 0 until the entire number have been transferred,exposed, and returned, when the plate D will come to the top, and ofcourse indicate to the sense of touch that all have been operated upon.

The combination, with the described light tight ease provided with twohinged lids, C C, and notch c, of the plate D, as and for the purposedescribed.
